ALEX
At ALEX, we build DeFi primitives targeting developers looking to build ecosystem on Bitcoin, enabled by Stacks. As such, we focus on trading, lending and borrowing of crypto assets with Bitcoin as the settlement layer and Stacks as the smart contract layer.

Rewards
Rewards by Threat Level
Mainnet assets:
Reward amount is 10% of the funds directly affected up to a maximum of:
$100,000Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.2. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.
All High and Critical Smart Contract bug reports require a PoC in order to be considered for a reward. Explanations and statements are not accepted as PoC and code is required.
Critical smart contract vulnerabilities are capped at 10% of economic damage, primarily taking into consideration funds at risk, but also PR and branding aspects, at the discretion of the team. However, there is a minimum reward of USD 20 000 paid in ALEX. Additionally, the maximum reward is capped at USD 100 000) paid in ALEX, even if 10% of the damage in USD equivalent is greater than the USD 100 000.
The following vulnerabilities are not eligible for a reward:
- All vulnerabilities marked in the CoinFabrik Security Review Pool / Equation, Launchpad / Vault / Reserve
- All vulnerabilities marked in the CoinFabrik Security Review DAO
- All vulnerabilities marked in the CoinFabrik Security Review Launchpad v1.1 / AutoALEX / Collateral Rebalancing Pool
- All vulnerabilities marked in the CoinFabrik Security Review Bridge Endpoints
- All vulnerabilities marked in the CoinFabrik Security Review Bridge backend and endpoints
- All vulnerabilities marked in the Least Authority Security Review
ALEX requires KYC to be done for all bug bounty hunters submitting a report and wanting a reward. The information needed are Name, Email address, Stacks wallet address, and Identity Proof (Passport, / Driving License / National ID). The collection of this information will be done by the ALEX team.
Payouts are handled by the ALEX team directly. Payouts are done in ALEX.
Program Overview
At ALEX, we build DeFi primitives targeting developers looking to build ecosystem on Bitcoin, enabled by Stacks. As such, we focus on trading, lending and borrowing of crypto assets with Bitcoin as the settlement layer and Stacks as the smart contract layer. At the core of this focus is the automated market making ("AMM") protocol, which allows users to exchange one crypto asset with another trustlessly.
For more information about ALEX, please visit https://alexgo.io/.
This bug bounty program is focused on their smart contracts and is focused on preventing:
- Thefts and freezing of principal of any amount
- Thefts and freezing of unclaimed yield of any amount
- Theft of governance funds
- Governance activity disruption
KYC required
The submission of KYC information is a requirement for payout processing.
Proof of Concept
Proof of concept is always required for all severities.
Prohibited Activities
- Any testing on mainnet or public testnet deployed code; all testing should be done on local-forks of either public testnet or mainnet
- Any testing with pricing oracles or third-party smart contracts
- Attempting phishing or other social engineering attacks against our employees and/or customers
- Any testing with third-party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)
- Any denial of service attacks that are executed against project assets
- Automated testing of services that generates significant amounts of traffic
- Public disclosure of an unpatched vulnerability in an embargoed bounty
- Any other actions prohibited by the Immunefi Rules
Feasibility Limitations
The project may be receiving reports that are valid (the bug and attack vector are real) and cite assets and impacts that are in scope, but there may be obstacles or barriers to executing the attack in the real world. In other words, there is a question about how feasible the attack really is. Conversely, there may also be mitigation measures that projects can take to prevent the impact of the bug, which are not feasible or would require unconventional action and hence, should not be used as reasons for downgrading a bug's severity.
Therefore, Immunefi has developed a set of feasibility limitation standards which by default states what security researchers, as well as projects, can or cannot cite when reviewing a bug report.
